Immune modulation by UV: Role of vitamin D

In this chapter, evidence for and evidence against the involvement of vitamin D in the immunoregulatory properties of UV radiation is presented.

Optimized 25-hydroxyvitamin D analysis using liquid-liquid extraction with 2D separation with LC/MS/MS detection, provides superior precision

The analysis of 25-hydroxyvitamin D3 (25(OH)D3) and related metabolites represents a considerable challenge for both clinical and research laboratories...

The current state of play of rodent models to study the role of vitamin D in UV-induced immunomodulation

Ultraviolet radiation (UVR) from sunlight is immunomodulatory and the main source of vitamin D for humans.

Vitamin D 3 deficiency enhances allergen-induced lymphocyte responses in a mouse model of allergic airway disease

In this study, using a mouse model, we determined whether vitamin D deficiency in utero and during early life modulated the severity of asthma.

Differences in control by UV radiation of inflammatory airways disease in naïve and allergen pre-sensitised mice

Exposure of skin to UV radiation (UVR) prior to allergen exposure can inhibit inflammatory airways disease in mice by reducing effector CD4+ T cells in both...

Ultraviolet irradiation of mice reduces the competency of bone marrow-derived CD11c+

Direct UV irradiation of dendritic cells and Langerhans cells reduces their Ag presenting ability. However, the effects of UV on CD11c(+) cells located...

UV exposure and protection against allergic airways disease

Asthma is a chronic inflammatory disease of the small and large conducting airway mucosa characterised by Th2 cell immunity.

UV light and COVID-19

Investigator: Nisali Gamage Project description We critically review new studies which are emerging that report findings related to the effects of UV

The inhibitory and inactivating effects of visible light on SARS-CoV-2: A narrative update

Prior to the coronavirus disease-19 pandemic, the germicidal effects of visible light were well known. This review provides an overview of new findings that suggest there are direct inactivating effects of visible light - particularly blue wavelengths on exposed severe acute respiratory syndrome coronavirus 2 virions, and inhibitory effects on viral replication in infected cells. These findings complement emerging evidence that there may be clinical benefits of orally administered blue light for limiting the severity of COVID-19.
